Comparison of Three Empirical Stomatal Conductance Models in Acacia Caven (Mol.) Under Drought Conditions
Stomatal conductance ( ) is the main controller of the plant-atmosphere interaction and a key feature to understand how natural vegetation copes with drought. Stomatal conductance empirical models base their performance ...
Effects of potassium and sodium supply on drought-adaptive mechanisms in Eucalyptus grandis plantations
A basic understanding of nutrition effects on the mechanisms involved in tree response to drought is essential under a future drier climate. A large-scale throughfall exclusion experiment was set up in Brazil to gain an ...
Water relations and carbon isotope composition in young plants of two provenances of Jatropha curcas L. subjected to water deficit.
(In: CONGRESSO DA REDE BRASILEIRA DE TECNOLOGIA DE BIODIESEL, 6.; CONGRESSO BRASILEIRO DE PLANTAS OLEAGINOSAS, ÓLEOS, GORDURAS E BIODIESEL, 9., 2016, Natal, RN. Biodiesel: 10 anos de pesquisa, desenvolvimento e inovação no Brasil: anais. Lavras: UFLA, 2016., 2016)
Gas exchange in lisianthus plants (Eustoma grandiflorum) submitted to different doses of nitrogen
(Acad Sci Czech Republic, Inst Experimental Botany, 2005-01-01)
The effect of different doses of nitrogen (N) on gas exchange, relative chlorophyll (Chl) amount, and the content of N in the aerial biomass of lisianthus was evaluated. The treatments consisted of six different concentrations ...
Root to leaf electrical signaling in avocado in response to light and soil water content
Phytomonitoring techniques for irrigation of avocado orchards indicate that plants respond very rapidly to fluctuations in soil water content. Root to leaf abscicic acid transport cannot fully explain the almost immediate ...
Cotton leaf gas exchange responses to irradiance and leaf aging
(Acad Sciences Czech Republic, Inst Experimental Botany, 2015-06-01)
Cotton (Gossypium hirsutum L.) net photosynthetic rate (P-N) decreased with leaf age and low irradiance, and the interaction of these factors might lead to decreased yields mainly in crops with a high plant density. Shade ...
Características fotossintéticas de genótipos de capim-elefante anão (Pennisetum purpureum Schum.), em estresse hídrico
The experiment was carried out aiming to evaluate the gas exchange of dwarf elephant grass genotypes under different hydric conditions, in a randomized design with three replications. Genotypes of dwarf elephant grass ...
Photosynthetic responses and proline content of mature and young leaves of sunflower plants under water deficit
In mature and young leaves of sunflower (Helianthus annuus L. cv. Catissol-01) plants grown in the greenhouse, photosynthetic rate, stomatal conductance, and transpiration rate declined during water stress independently ...
